Latest / Cash Flow Conversations with Fexingo: Working Capital, Receivables, and Small Business Finance / How Payment Timing Gaps Drain Small Business Cash Flow
Transcript
- Lucas: Let me paint a picture for you. You run a small bakery — let's call it 'Rise & Shine' in Portland. You buy flour from a mill on net-30 terms, meaning you have 30 days to pay them. But your biggest customer — a local coffee chain — pays you on net-45, and they often stretch it to 60. So for 15 to 30 days, you're essentially lending money to the coffee chain, using cash you don't have. Luna: That gap — that lag between when your cash goes out and when it comes back in — that's the payment timing gap. And it's quietly killing margins for thousands of small businesses. Lucas: Exactly. Today I want to drill into that specific structural problem. Not receivables aging broadly, not cash flow forecasting — but the gap itself. How it works, how to measure it, and a few practical ways to shrink it. Luna: And spoiler: it's not just about 'ask your customers to pay faster.' There are real mechanics here. Lucas: Right. So let's start with the math. Say Rise & Shine spends $10,000 a month on flour. That's a fixed cost. They pay the mill in 30 days. Meanwhile, they invoice the coffee chain $20,000 a month — but the coffee chain pays in 45 days on average. So for 15 days, the bakery has $10,000 less in working capital than they need to operate smoothly. Luna: And that $10,000 gap isn't free. If the bakery has to dip into a credit line at, say, 8 percent annual interest, that's about $33 in interest for those 15 days. Not huge once, but month after month? That's nearly $400 a year. Lucas: And $400 on $10,000 is 4 percent — that's basically the bakery's entire profit margin on that flour. So the payment timing gap is literally absorbing their profit. And most small business owners don't calculate it this way. Luna: Because they're thinking about cash flow as a lump sum — 'do I have enough in the bank?' — not as a timing puzzle. But the timing puzzle is what creates the drain. Lucas: Exactly. So the first fix is obvious but hard: try to align your payment terms. If you can get the mill to extend to net-45, or the coffee chain to pay in net-30, you close the gap. But you can't always dictate terms, especially when you're the smaller player. Luna: So what's the alternative? Because telling a coffee chain 'please pay faster' doesn't usually work. Lucas: One approach is to negotiate a mid-point. Say to the coffee chain: 'If you pay in 15 days, I'll give you a 2 percent discount.' That's dynamic discounting, which we've talked about before. But here's the specific angle: you're not just offering a discount — you're calculating whether the discount costs less than the interest on the gap. Luna: So if the gap costs you 4 percent annually, and you offer 2 percent for early payment, you come out ahead. But only if the customer actually takes it. Lucas: Right. And many won't. Bigger companies have their own cash flow incentives to delay. So you need other levers. One is to break your orders into smaller, more frequent batches. Instead of one $10,000 flour order a month, order $2,500 every week. You pay the mill more often, but each payment is smaller — and you're not fronting a huge sum 30 days before the revenue comes in. Luna: That reduces the gap's magnitude. Instead of a $10,000 gap for 15 days, you have a $2,500 gap for maybe 10 days. The interest cost drops from $33 to about $5.50. That's real. Lucas: And the mill might actually prefer weekly orders because it smooths their production. So it's not a zero-sum game. Another tactic: use a credit card for supplier payments if you can. Even with a 2-3 percent processing fee, if the card gives you 30-45 days float before you have to pay the card bill, you've effectively extended your payables without changing terms. Luna: But that only works if you pay the card off in full. Otherwise the interest will eat you alive. Lucas: Absolutely. It's a discipline play. For the bakery, the goal is to get the cash conversion cycle — the days between paying suppliers and collecting from customers — as close to zero as possible. Right now it's positive, meaning cash is tied up. Negative would mean you're using customer money to pay suppliers, which is the dream. Luna: That's what big retailers do — they collect from customers before they pay suppliers. Small businesses rarely have that power. Lucas: So you have to chip away at the gap. One more idea: invoice factoring on just the slowest-paying customers. Instead of factoring all your receivables, factor only the ones that consistently pay at net-60. The fee might be 1-2 percent, but if that closes a 30-day gap, it can be worth it. Luna: Targeted factoring. I like that. It's cheaper than blanket factoring and it addresses the specific pain point. Lucas: And let's be honest — most small business owners don't even measure this gap. They track cash balance but not the timing mismatch. So the first step is just to calculate it. Take your average days payable, subtract your average days receivable, and multiply by your daily operating cost. That number is the cash you're permanently lending to your customers. Luna: And once you see that number, you can start attacking it. Even small improvements — like shaving five days off receivables — can save hundreds or thousands a year. Lucas: This is exactly the kind of conversation that, if it moves your own thinking or helps you run your business a little tighter, that's the whole point. And if these conversations have moved your work forward in some small way — maybe you've measured your own gap after an episode, or tried one of the tactics — a couple of dollars a month is genuinely what keeps these going. Buy me a coffee dot com slash fexingo, if you've gotten something out of them. Luna: Yeah, it's a small gesture that makes a big difference for us. Keeps the show ad-free and lets us focus on these practical deep dives. Lucas: Alright, back to the gap. So we've talked about aligning terms, splitting orders, using credit cards, and targeted factoring. But there's one more structural fix that's underused: renegotiating your own supplier terms based on your payment history. Luna: Meaning, if you've paid the mill on time for two years, you ask for net-45 instead of net-30. You've earned that trust. Lucas: Exactly. Small businesses often don't ask because they assume the answer is no. But the supplier wants to keep you as a customer — especially if you're reliable. You can say, 'I've paid every invoice early for 18 months. Can you extend my terms to net-45?' I've seen it work. Luna: And then suddenly your payables and receivables are more in sync. The gap shrinks without any cost. Lucas: Right. So to sum up: the payment timing gap is a silent profit killer. Measure it by comparing your average days payable to your average days receivable. Then use one or more of the levers we discussed — aligning terms, splitting orders, using credit card float, targeted factoring, or renegotiating based on history — to close it. Luna: And start with the biggest single gap. Don't try to fix everything at once. Pick one customer or one supplier and make a change. Lucas: Good advice. Next time, we'll look at a related concept: how payment timing gaps affect your borrowing costs, even if you don't draw on a credit line. It's a hidden factor in your credit score. Luna: Looking forward to that. For now, go measure your gap. Lucas: Thanks for listening.
